I hate hype. It's very hard for a movie to live up to its hype and when it doesn't you just leave feeling underwhelmed and disappointed, whereas if you didn't have the hype and the expectations, you would've set your bar lower and enjoyed the movie a lot more.
Now, none of that actually applies to Batman because it did live up to its hype, in my mind. But I notice that effect is still present. I set the bar really high, it met it, and so I said "Yeah, that's a good movie." But if I'd walked into that theater without any expectations, I would've been blown away and wouldn't be able to form a coherent thought.
So yeah. Go and see it if you haven't yet. It's okay.
